Much House Can I Afford Calculator

Use this How Much House Can I Afford Calculator to estimate the maximum home price and mortgage that may fit your income, down payment, interest rate, monthly debt payments and housing expenses. Choose Canada or the United States, enter your financial information, and the calculator will estimate your home-buying range along with your mortgage payment, property taxes, insurance, debt ratios and total monthly housing cost.

Mortgage qualification and true household affordability are not always the same thing. A lender may calculate how much you qualify to borrow using gross income and debt ratios, while your personal budget also needs to cover food, transportation, savings, repairs, childcare, utilities and other expenses. Use the calculator to test different incomes, down payments, mortgage rates and monthly costs before you start comparing homes.

How to Use the How Much House Can I Afford Calculator

Start by choosing Canada or the United States. Mortgage qualification works differently in the two countries, so the calculator changes its default assumptions depending on the country you select.

Enter your gross annual household income. Gross income means income before income tax and payroll deductions. If two borrowers will apply for the mortgage together and both incomes will be accepted by the lender, enter the combined annual qualifying income.

Next, enter the money you intend to use as your down payment. Keep closing costs, moving expenses and emergency savings separate rather than assuming every dollar you have saved will be available for the down payment.

Enter the mortgage rate you expect to receive and choose the amortization or loan term. Then enter other monthly debt payments such as car loans, student loans, credit cards, personal loans and lines of credit.

Simple Estimate is designed for a fast calculation. Advanced Estimate lets you change property taxes, insurance, utilities, condo or HOA fees, mortgage insurance and the debt-ratio limits used by the calculator.

Press Calculate How Much House I Can Afford. The result shows an estimated maximum home price along with the estimated mortgage, monthly mortgage payment, total housing cost, down-payment percentage and applicable debt ratios.

After you have an estimated purchase price, use our Mortgage Calculator to calculate a specific mortgage payment and view how the balance changes over time.

How Much House Can I Afford?

The amount of house you can afford depends on several financial factors working together. Your salary matters, but salary alone cannot produce an accurate home-buying budget. The down payment, mortgage interest rate, existing monthly debt, property tax, heating, insurance and condo or HOA fees can all change the result.

Two households can earn exactly the same amount but qualify for very different mortgages. A household earning $120,000 with no consumer debt and a $150,000 down payment is in a very different position from a household earning $120,000 with two vehicle payments, credit-card balances and only $30,000 saved.

Interest rates also have a major effect. A mortgage balance that creates a manageable payment at one interest rate may produce a much larger payment after rates increase. Since mortgage affordability calculations are based partly on the required monthly payment, higher rates generally reduce purchasing power.

A home affordability calculator therefore works in the opposite direction from a normal mortgage payment calculator. Instead of entering a home price and asking what the mortgage payment will be, you enter your finances and ask what home price those finances may support.

How Home Affordability Is Calculated

The calculator begins by converting annual gross household income into gross monthly income. A household earning $120,000 per year has gross monthly income of $10,000.

It then applies the housing ratio and total debt ratio. These ratios determine how much of gross income can be used for qualifying housing expenses and how much can be used for housing plus other debts.

Property taxes, heating, insurance and condo or HOA fees consume part of the monthly housing allowance. Existing debts consume part of the total-debt allowance.

The remaining room is used to estimate the mortgage payment that can fit within both limits. The calculator then works backward from that payment to determine the mortgage principal supported by the selected mortgage rate and amortization.

The down payment is then included to estimate a maximum purchase price. Canada mode also checks minimum-down-payment rules and calculates an estimated mortgage-insurance premium when required.

How Income Affects How Much House You Can Afford

Mortgage qualification usually begins with gross qualifying income rather than the amount deposited into your bank account after taxes. Gross income is what you earn before deductions.

Higher qualifying income generally supports a larger mortgage because the allowable housing payment increases when the same debt ratio is applied to a larger income.

For example, 39% of $8,000 is $3,120 while 39% of $10,000 is $3,900. A household earning $10,000 per month therefore has more room for qualifying housing expenses under the same 39% ratio.

Not every type of income is necessarily treated the same way. Salary may be straightforward, while overtime, bonuses, commissions, self-employment income and rental income may require documentation or a history of earnings before a lender includes the entire amount.

The calculator assumes the income you enter is the gross annual income available for qualification. If part of your income is variable, run several scenarios to see how a lower qualifying-income amount would affect the result.

If you want to compare gross salary with take-home earnings, use the Paycheck Calculator. Mortgage qualification may use gross income, but your personal budget still needs to work with your actual after-tax cash flow.

How Your Down Payment Changes Home Affordability

A larger down payment can increase the home price you can purchase because it reduces the amount that needs to be borrowed. If two buyers purchase the same home but one contributes twice as much cash, the second buyer needs a smaller mortgage.

The down-payment percentage also affects loan-to-value. Loan-to-value compares the mortgage principal with the value of the property. A $400,000 mortgage on a $500,000 property represents an 80% loan-to-value ratio before any financed mortgage-insurance premium.

Mortgage insurance is another reason down payment matters. In Canada, eligible mortgages with less than 20% down will generally require mortgage default insurance. Some U.S. mortgages can also require private mortgage insurance or another insurance premium when the down payment is relatively small.

There is also a point where income rather than cash becomes the limiting factor. A buyer could have a very large down payment and still be unable to support the mortgage payment required for a much more expensive home.

Do not automatically use every dollar of savings for the down payment. Home buyers also need to consider legal fees, inspections, moving expenses, furniture, emergency savings and repairs.

How Mortgage Rates Affect How Much House You Can Afford

Mortgage interest rates directly affect purchasing power because a higher rate creates a larger payment on the same mortgage balance.

If your maximum qualifying monthly payment stays the same, a higher interest rate means that payment can support less mortgage principal. A lower interest rate means the same monthly payment can support more principal.

The difference becomes significant because mortgages are large loans with long repayment periods. A change of one percentage point can alter the monthly payment by hundreds of dollars on a large mortgage.

Try calculating affordability at several interest rates. Use your expected rate first, then calculate again at a rate 0.5% and 1% higher. This shows how sensitive your home-buying budget is to rate changes.

Once you know the mortgage amount you want to test, the Mortgage Estimate Calculator can help you compare monthly payments directly.

How Monthly Debt Reduces Home-Buying Power

Existing debt is one of the biggest reasons two people with the same income can receive different affordability results.

Imagine a household earns $10,000 gross per month and uses a 44% total-debt limit. Forty-four percent of $10,000 is $4,400. If the household already has $1,200 of monthly debt payments, those payments consume part of the $4,400 allowance before the new mortgage is added.

Common debts can include vehicle payments, student loans, personal loans, credit cards and lines of credit. The exact way each debt is treated depends on the lender and mortgage program.

This is why paying off a loan with a large monthly payment can sometimes improve mortgage affordability considerably. Removing a $700 monthly car payment creates more room in a total-debt calculation every month.

How Much House Can I Afford in Canada?

Canadian mortgage affordability commonly uses Gross Debt Service and Total Debt Service ratios. Borrowers may also need to qualify at a mortgage interest rate higher than the actual contract rate.

The Canada mode in this calculator uses separate GDS and TDS limits. It increases the estimated purchase price until one of those limits is reached or the available down payment becomes too small to meet the minimum-down-payment requirement.

The calculator also estimates mortgage default insurance when the down payment is below 20% and the home price remains within the insured-mortgage range used by the calculation.

Canadian mortgage payment calculations in this tool use an equivalent monthly rate based on semi-annual compounding rather than simply dividing the annual nominal rate by 12.

What Is the GDS Ratio?

GDS stands for Gross Debt Service. It compares qualifying housing expenses with gross monthly household income.

The calculator uses 39% as the default Canadian GDS limit. Housing costs in the calculation include the qualifying mortgage payment, property taxes, heating and 50% of the entered condo fee.

If household income is $10,000 per month, a 39% limit equals $3,900. That does not mean the mortgage payment itself can necessarily be $3,900. Property taxes, heating and applicable condo costs must fit inside the same amount.

What Is the TDS Ratio?

TDS stands for Total Debt Service. It includes the housing expenses used in GDS plus other qualifying monthly debt obligations.

The calculator uses 44% as its default Canadian TDS limit. If a household earns $10,000 per month, 44% equals $4,400 of total modeled housing and debt obligations.

If the household already has $800 of other monthly debt, approximately $3,600 remains before the 44% total-debt limit is reached. The GDS limit can still be lower, which means the calculator has to satisfy both conditions.

Canadian Mortgage Stress Test

The Canadian mortgage stress test is designed to test whether borrowers could still support their mortgage at an interest rate above the contract rate.

When the stress-test box is turned on, the calculator uses the greater of 5.25% or the entered mortgage rate plus 2 percentage points as the qualifying rate.

If the mortgage rate is 4.5%, adding two percentage points produces 6.5%. Since 6.5% is greater than 5.25%, the qualifying payment is calculated at 6.5%.

If the contract rate is 3%, adding two points gives 5%. In that case the 5.25% floor is higher, so 5.25% is used for qualification.

The qualifying mortgage payment can therefore be higher than the actual mortgage payment shown in the results. The actual payment uses the mortgage rate you entered, while GDS and TDS use the qualifying rate when the stress test is enabled.

For the current federal qualifying-rate framework, see the Office of the Superintendent of Financial Institutions.

Minimum Down Payment in Canada

The minimum down payment for a Canadian home depends on the purchase price. The calculator applies the current federal thresholds when testing potential purchase prices.

• For a home priced at $500,000 or less, the minimum down payment is 5%.
• For a home above $500,000 and below $1.5 million, the minimum is 5% of the first $500,000 plus 10% of the portion above $500,000.
• For a home priced at $1.5 million or more, the calculator requires a 20% down payment.

Minimum Down Payment on a $600,000 Home

Five percent of the first $500,000 is $25,000. Ten percent of the remaining $100,000 is $10,000. The minimum down payment is therefore $35,000.

Minimum Down Payment on a $1,000,000 Home

Five percent of the first $500,000 is $25,000. Ten percent of the remaining $500,000 is $50,000. The total minimum down payment is $75,000.

The Financial Consumer Agency of Canada publishes the current federal minimum-down-payment requirements.

Mortgage Loan Insurance in Canada

An eligible Canadian mortgage with less than 20% down will generally require mortgage default insurance. The insurance protects the lender against mortgage default rather than providing property insurance for the homeowner.

The insurance premium is based largely on the loan-to-value ratio. As the amount borrowed approaches the value of the home, the premium percentage generally increases.

The calculator estimates an insurance premium and adds it to the mortgage principal where applicable. This is why the mortgage used for payment calculations can be slightly higher than the home price minus the cash down payment.

The calculator uses an estimated rate of 2.80% for loan-to-value above 80% through 85%, 3.10% above 85% through 90%, and 4.00% above 90% through 95%. For a modeled 30-year insured amortization, a 0.20 percentage-point surcharge is added.

Actual mortgage-insurance premiums and eligibility can depend on the mortgage product, insurer and borrower. Provincial sales tax on insurance premiums, where applicable, is not included in this estimate.

How a 30-Year Mortgage Changes Affordability

A longer amortization spreads repayment across more months. That lowers the scheduled payment on the same amount of mortgage principal.

Because mortgage qualification is partly based on the monthly payment, a longer amortization can allow a larger mortgage to fit within a particular debt ratio.

The trade-off is total interest. Borrowing the same amount for a longer period normally means paying more interest over the life of the mortgage.

If you want to compare lifetime borrowing costs rather than only the monthly payment, use the Mortgage Interest Paid Over Time Calculator.

How Much House Can I Afford in the United States?

The United States side of the calculator uses a housing expense ratio and a total debt-to-income ratio. The basic principle is similar to GDS and TDS: a certain portion of gross monthly income is available for housing, while another limit applies after other debt payments are included.

There is not one universal DTI limit used by every U.S. lender or mortgage product. Conventional mortgages, FHA loans, VA loans and other products can use different underwriting rules.

Simple mode therefore uses 28% for housing and 36% for total debt as general planning assumptions rather than presenting those values as mandatory limits. Advanced mode lets you replace them with other percentages.

U.S. housing costs in the calculator include principal and interest, property taxes, homeowners insurance, HOA fees and the PMI amount you enter.

What Is Debt-to-Income Ratio?

Debt-to-income ratio, or DTI, compares monthly debt payments with gross monthly income.

If gross monthly income is $8,000 and qualifying monthly debt payments total $3,000, the debt-to-income ratio is 37.5%.

A lower DTI means a smaller percentage of income is already committed to debt. A higher DTI means more income is required to service debt each month.

Since U.S. mortgage programs can use different DTI limits, Advanced mode is useful when you have more specific underwriting information from a lender.

How Much House Can I Afford Based on My Income?

Income-specific questions are common because salary is often the first number a home buyer knows. The problem with simple salary multiples is that they ignore debt, down payment, mortgage rates and property expenses.

The same $100,000 salary can support very different home prices depending on whether the buyer has no debt or $1,500 of monthly debt, whether the down payment is $25,000 or $150,000, and whether the mortgage rate is 3.5% or 6.5%.

How Much House Can I Afford on $50,000 a Year?

A $50,000 annual household income is approximately $4,167 gross per month. Enter $50,000 into the calculator and add your actual debt payments, available down payment and expected mortgage rate.

How Much House Can I Afford on $60,000 a Year?

A $60,000 annual household income is $5,000 gross per month. A buyer with little debt can generally devote more of the total-debt allowance to housing than someone with a large vehicle payment or student loan.

How Much House Can I Afford on $75,000 a Year?

A $75,000 household income equals $6,250 gross per month. Property taxes and mortgage rates can make a noticeable difference at this income because both reduce the portion of the monthly allowance available for mortgage principal.

How Much House Can I Afford on $80,000 a Year?

An $80,000 income is approximately $6,667 gross per month. Enter that amount along with your actual down payment and debts rather than relying on a rule stating that a home should cost a fixed multiple of salary.

How Much House Can I Afford on $100,000 a Year?

A $100,000 annual household income equals approximately $8,333 gross per month. How much of that income can support housing depends on the applicable debt ratios and monthly obligations.

How Much House Can I Afford on $120,000 a Year?

A $120,000 household income equals $10,000 gross per month. Under a 39% housing-ratio assumption, the theoretical maximum qualifying housing expense is $3,900 per month before considering the separate total-debt restriction.

The full $3,900 is not necessarily available for the mortgage payment. Property tax, heating and applicable condo costs also use part of the housing allowance.

How Much House Can I Afford on $150,000 a Year?

A $150,000 annual household income is $12,500 gross per month. Higher income generally increases mortgage capacity, but a large amount of consumer debt can still materially lower the result.

How Much House Can I Afford on $200,000 a Year?

A $200,000 household income is approximately $16,667 gross per month. At higher incomes, the down payment can become an important limiting factor because the estimated purchase price may approach thresholds where insured-mortgage rules change.

How Much House Can I Afford on $250,000 a Year?

A $250,000 annual household income is approximately $20,833 gross per month. Even at this income level, mortgage rates, property taxes, debt payments and the amount available for a down payment can move the result substantially.

Costs to Consider Beyond the Mortgage

A mortgage is usually the largest homeownership expense, but it is not the only one. Looking only at principal and interest can make a property appear much cheaper than it really is.

Property Taxes

Property tax varies considerably by city and property. The calculator estimates property tax as a percentage of home value so the amount changes automatically as the estimated home price changes.

At a 1% annual property-tax rate, a $500,000 home would produce an estimated $5,000 annual tax bill, or approximately $417 per month.

Home Insurance

Homeowners insurance is another recurring expense. Premiums depend on the property, location, deductible, coverage level and insurer.

Heating and Utilities

Heating costs depend on climate, home size, insulation, heating equipment and energy prices. Canada mode specifically includes heating in the modeled debt-service calculation.

Condo and HOA Fees

A recurring condo or HOA fee can materially change the monthly cost of owning a property. A $600 monthly condo fee adds $7,200 per year to the cost of ownership even though it is not part of the mortgage principal.

Canada mode uses half of the entered condo fee in the modeled GDS and TDS housing expense while the entire condo fee is included in the displayed actual monthly housing cost.

Maintenance and Repairs

The mortgage qualification calculation does not automatically deduct a future maintenance allowance. Your personal budget still needs to account for repairs and replacement costs.

Roofs, furnaces, appliances, plumbing, electrical systems, landscaping and unexpected repairs can create large irregular expenses.

Closing Costs

Closing expenses are separate from the down payment. Depending on the transaction and location, these can include legal fees, title costs, inspections, appraisals, taxes and adjustments for prepaid expenses.

If you have $80,000 saved but expect to need $15,000 for closing, moving and immediate expenses, entering $65,000 as the down payment may provide a more realistic estimate.

How Much You Qualify For vs. How Much You Can Comfortably Afford

A mortgage qualification calculation and a personal household budget answer two different questions.

Qualification asks how much housing and debt fit within the underwriting rules being applied. Personal affordability asks how much housing cost you can comfortably carry while still paying for everything else in your life.

A lender-style debt ratio does not know how much you spend on groceries, childcare, travel, retirement savings, fuel, medical expenses, hobbies, education or family support.

You may therefore qualify for a larger mortgage than you actually want. Choosing a home below the maximum can leave additional room for savings and unexpected expenses.

The opposite is also important. An online calculator showing that a price fits the mathematical assumptions does not guarantee approval from a lender.

If you are deciding between buying and continuing to rent, use the Rent vs Buy Calculator to compare the two choices over time.

How to Increase How Much House You Can Afford

The calculator makes it easy to see which variables have the greatest effect on your estimate. Change one input at a time and recalculate so you can see what actually moves the result.

• Increase the down payment: A larger down payment reduces the mortgage required.
• Reduce monthly debt: Paying off a car loan or other recurring payment can free up room under the total debt ratio.
• Increase qualifying income: Higher documented gross income increases the amount available within the debt ratios.
• Obtain a lower mortgage rate: A lower rate reduces the payment required for the same principal.
• Use a longer amortization when appropriate and eligible: A longer amortization reduces the scheduled payment but can increase lifetime interest.
• Choose a home with lower property taxes: Taxes use part of the monthly housing allowance.
• Choose lower condo or HOA fees: Recurring fees reduce available monthly cash flow.
• Buy below your maximum: The largest amount you may qualify for does not have to become your purchase budget.

Why Paying Off Debt Can Increase Mortgage Affordability

Paying off debt can improve mortgage affordability because it removes a recurring payment from the total-debt calculation.

Suppose you have a vehicle loan with a $700 monthly payment. Eliminating the payment can create $700 of additional monthly room before reaching a total-debt limit.

That does not automatically mean paying off the loan is always better than putting the same cash toward a down payment. The better choice depends on the remaining loan balance, monthly payment, down-payment rules and your available cash.

How Property Taxes Reduce Mortgage Affordability

Property tax matters because it consumes some of the income that could otherwise support a mortgage payment.

Two homes can have the same purchase price but different affordability results if their property taxes are significantly different.

A $600,000 home with a 1% annual property-tax assumption produces approximately $500 per month of tax. At a 2% rate, that amount becomes approximately $1,000 per month.

That additional $500 per month leaves less room for the mortgage payment under a fixed housing-expense ratio.

How Condo Fees Affect Home Affordability

Condo fees can have a large effect because they are recurring monthly costs that remain even after the mortgage principal is eventually paid off.

A lower-priced condo with a large monthly fee can sometimes have a similar total monthly cost to a more expensive property without that fee.

Some condo fees include services a detached homeowner would otherwise pay separately, such as common-area maintenance, exterior repairs or certain utilities. Compare what is actually included rather than looking only at the monthly fee.

Mortgage Affordability Calculator vs. Mortgage Payment Calculator

A mortgage payment calculator starts with a mortgage amount and determines the payment. A mortgage affordability calculator starts with your finances and estimates the mortgage amount.

For example, you might enter a $500,000 mortgage into a payment calculator to find the monthly payment at 4.5%. With this affordability calculator, you enter income, debt and down payment and ask whether a mortgage around that size fits the assumptions.

Both tools are useful, but they answer different questions. Affordability is useful early in the home search. Payment calculations become more important once you are comparing specific properties.

How Much Mortgage Can I Afford?

The mortgage amount and home price are not the same. Your down payment covers part of the purchase price, while the mortgage finances the remainder.

If a home costs $600,000 and you put down $120,000, the base mortgage is $480,000 before any other financed amount.

When mortgage default insurance is financed into a Canadian high-ratio mortgage, the actual mortgage used for payment calculations can be slightly larger than purchase price minus down payment.

How Much House Can I Afford With No Debt?

Having no monthly consumer debt usually increases mortgage borrowing capacity because more of the total-debt allowance remains available for housing.

However, zero debt does not eliminate the housing-specific limit. Property tax, heating and condo costs still need to fit within the housing ratio.

In Canada, GDS may therefore become the limiting factor even when TDS has plenty of room.

How Much House Can Two Incomes Afford?

If two borrowers are applying together and both incomes qualify, combine the two gross annual incomes.

If one borrower earns $80,000 and the other earns $60,000, enter $140,000 as gross household income.

Combine the debts as well. If one borrower has a $600 monthly vehicle payment and the other has a $300 student-loan payment, enter $900 of other monthly debt.

Does Credit Score Affect How Much House I Can Afford?

Credit score is not included as a direct numerical input because its effect is not represented by one universal affordability formula.

Credit can still influence mortgage eligibility, interest rates, mortgage products and pricing. Because the interest rate directly affects affordability, credit can indirectly change the amount of house you can purchase.

If your expected credit profile means you are likely to receive a mortgage rate higher than the lowest advertised rate, enter the rate you realistically expect to receive.

How Closing Costs Affect Your Home-Buying Budget

The calculator assumes the down-payment amount entered is available specifically for the down payment. It does not automatically deduct closing costs.

If you have $100,000 available but expect to need $20,000 for legal fees, moving expenses, inspection costs and other closing expenses, you may want to enter $80,000 rather than the full $100,000.

How Amortization Changes Home Affordability

A longer amortization reduces the scheduled payment for the same mortgage principal because repayment is spread over more months.

Since affordability calculations use the monthly mortgage payment, a longer amortization can increase the principal supported by the same income.

The cost is additional interest. Lower monthly payments do not necessarily mean a cheaper mortgage overall.

How to Compare Different Home Prices

Once you have an estimated maximum, compare several purchase prices below it rather than treating the maximum as a target.

If the calculator produces $700,000, compare the monthly costs of $550,000, $600,000, $650,000 and $700,000 homes. The difference may be several hundred dollars per month.

If you need to calculate down-payment percentages or compare percentage changes between two prices, use the Percentage Calculator.

Why Your Bank May Give You a Different Number

No online affordability calculator can duplicate every rule used by every bank, credit union or mortgage lender.

A lender may calculate variable income differently, use a different heating estimate, apply different rules to credit-card balances or lines of credit, or use the actual property taxes associated with the home you are purchasing.

The lender may also consider credit history, employment stability, property type, source of down payment, mortgage program and documentation requirements.

Use the calculator for initial planning and scenario comparisons rather than treating the result as a guaranteed mortgage approval.

How Much House Can I Afford Calculator FAQ

Final Thoughts

The question “how much house can I afford?” cannot be answered accurately from salary alone. Home affordability depends on income, down payment, debt, mortgage rates, amortization, property taxes, insurance, utilities and other housing costs working together.

Use Canada mode to estimate affordability with GDS, TDS, minimum-down-payment rules, mortgage insurance and the Canadian mortgage stress test. Use United States mode to model housing and total debt-to-income ratios while adjusting the assumptions to fit the mortgage program you are considering.

Once you have an estimated maximum home price, calculate several lower purchase prices as well. A lower mortgage can leave considerably more room for savings, repairs, travel and unexpected expenses even when a lender would allow you to borrow more.

The calculator is designed to establish a realistic home-buying range before you move on to individual listings and lender approval. Use the estimate together with your personal monthly budget so the home you choose works not only in a mortgage calculation but in everyday life as well.
